The game started with both sides right at it amid a good derby atmosphere. Luca Connell shot wide for the hosts before Glenn Middleton fired the game's first attempt on target straight at home stopper Owen Goodman. Jack Senior then glanced a header wide from a corner before the game hit a lull.
David McGoldrick awoke the contest from its slumber as he tried his luck from distance, testing Thimothee Lo-Tutala for the hosts' first effort on target as the sides went in level at the break. Reyes Cleary drilled a shot straight at Lo-Tutala just after the restart as Barnsley came out with much more impetus.
Rovers were then presented with a golden chance to go in front when sub Hakeeb Adelakun - who had only been on the pitch a matter of minutes - was fouled in the box. Up stepped Elliot Lee with a clinical penalty to open the scoring.
Barnsley then rallied but in truth never really looked like equalising. The best they mustered was a shot from ex-loanee Patrick Kelly that was shovelled away well by Lo-Tutala to seal the derby spoils.
Here's how we rated the Rovers players at Oakwell:
9. Glenn Middleton 6
Deployed on the right, in Molyneux's absence. Had an early sighter straight at goal and switched flanks with Gibson throughout. Hooked just before hour. Photo: Howard Roe/AHPIX LTD
10. Elliot Lee 7
Some exquisite touches and bits of control. Kept a cool head to fire home the penalty right in front of the jubilant away end. Photo: Howard Roe/AHPIX LTD
11. Brandon Hanlan 6
Tough time of it as nothing seemed to stick and despite lowest amount of touches of any player to complete the 90, he stuck to his task and made a nuisance of himself all afternoon. Photo: Howard Roe/AHPIX LTD
12. Hakeeb Adelakun 7
Came on for Middleton and within minutes of his introduction he'd won a penalty after being fouled in the box by Corey O'Keeffe. Some lovely displays of his trickery. Photo: Howard Roe/AHPIX LTD
